As described in greater detail below, provided are methods and systems for controlling content transmitted to a user location. In an aspect, a data stream transmitted to the user location can comprise a repeatedly embedded placement signal to indicate that a particular content should be transmitted to the user location.

FIG. 1 illustrates various aspects of an exemplary network environment in which the present methods and systems can operate. Some aspects of the present disclosure relate to methods and systems for content control. Those skilled in the art will appreciate that present methods may be used in systems that employ both digital and analog equipment. One skilled in the art will appreciate that provided herein is a functional description and that the respective functions can be performed by software, hardware, or a combination of software and hardware.

The network 100 can comprise a central location 101 (e.g., a headend, or processing facility), which can receive content (e.g., data, input programming) from multiple sources. The central location 101 can combine the content from the various sources and can distribute the content to user (e.g., subscriber) locations (e.g., location 119) via distribution system 116.

In an aspect, the central location 101 can receive content from a variety of sources 102 a, 102 b, 102 c. The content can be transmitted from the source to the central location 101 via a variety of transmission paths, including wireless (e.g. satellite paths 103 a, 103 b) and terrestrial path 104. The central location 101 can also receive content from a direct feed source 106 via a direct line 105. Content may also be created at the central location 101. Other input sources can comprise capture devices such as a video camera 109 or a server 110. The signals provided by the content sources can comprise a single content item or a multiplex that comprises several content items.

The central location 101 can comprise one or a plurality of receivers 111 a, 111 b, 111 c, 111 d that are each associated with an input source. For example, MPEG encoders such as encoder 112, are included for encoding/transcoding local content or a video camera 109 feed. As a further example, a data packaging device, such as a fragmentor, can be integrated with the encoder 112 (or separate and in communication with the encoder 112) to package the encoded/transcoded content. In an aspect, the encoder 112 and/or fragmentor can repeatedly embed markers, flags, and signals into the content data stream for processing by downstream devices. A switch 113 can provide access to server 110, which can be, for example, a pay-per-view server, a data server, an internet router, a network system, and/or a phone system. Some signals may require additional processing, such as signal multiplexing, prior to being modulated. Such multiplexing can be performed by multiplexer (mux) 114.

The central location 101 can comprise one or a plurality of modulators, 115 a, 115 b, 115 c, and 115 d, for interfacing to the distribution system 116. The modulators can convert the received content into a modulated output signal suitable for transmission over the distribution system 116. The output signals from the modulators can be combined, using equipment such as a combiner 117, for input into the distribution system 116.

A control system 118 can permit a system operator to control and monitor the functions and performance of network 100. The control system 118 can interface, monitor, and/or control a variety of functions, including, but not limited to, the channel lineup for the television system, billing for each user, and/or conditional access for content distributed to users. Control system 118 can provide input to the modulators for setting operating parameters, such as system specific MPEG table packet organization or conditional access information. The control system 118 can be located at central location 101 or at a remote location.

The distribution system 116 can distribute signals from the central location 101 to user locations, such as user location 119. The distribution system 116 can be an optical fiber network, a coaxial cable network, a hybrid fiber-coaxial network, a wireless network, a satellite system, a direct broadcast system, or any combination thereof. There can be a multitude of user locations connected to distribution system 116. At user location 119, a decoder 120, such as a gateway or home communications terminal (HCT) can decode, if needed, the signals for display on a display device, such as on a display device 121 such as a television set (TV), a mobile device, or a computer monitor. Those skilled in the art will appreciate that the signal can be decoded in a variety of equipment, including an HCT, a computer, a TV, a monitor, or satellite dish. In an exemplary aspect, the methods and systems disclosed can be located within, or performed on, one or more HCT's, display devices 121, central locations 101, DVR's, home theater PC's, and the like. As an example, the decoder 120 can receive and process the embedded markers, flags, and signals in the content data stream for controlling a content received by the decoder 120.

In an aspect, user location 119 is not fixed. By way of example, a user can receive content from the distribution system 116 on a mobile device such as a laptop computer, PDA, smartphone, GPS, vehicle entertainment system, and/or portable media player. The network of FIG. 1 is illustrative only and other types of networks and configurations may be used to implement the disclosure.

In an aspect, the methods and systems can utilize digital audio/video compression such as MPEG, or any other type of compression. The Moving Pictures Experts Group (MPEG) was established by the International Standards Organization (ISO) for the purpose of creating standards for digital audio/video compression. The MPEG experts created the MPEG-1 and MPEG-2 standards, with the MPEG-1 standard being a subset of the MPEG-2 standard. The combined MPEG-1, MPEG-2, MPEG-4, and subsequent MPEG standards are hereinafter referred to as MPEG. In an MPEG encoded transmission, content and other data are transmitted in packets, which collectively make up a transport stream. In an exemplary aspect, the present methods and systems can employ transmission of MPEG packets. However, the present methods and systems are not so limited, and can be implemented using other types of transmission and data.

The output of a single MPEG audio and/or video coder may be a transport stream, comprised of one or more elementary streams. An elementary stream is an endless near real-time signal. For convenience, the elementary stream may be broken into data blocks of manageable size, forming a packetized elementary stream (PES). These data blocks need header information to identify the start of the packets and must include time stamps because packetizing disrupts the time axis. For transmission and digital broadcasting, for example, several programs and their associated PESs can be multiplexed into a multi-program transport stream. A multi-program transport stream has a program clock reference (PCR) mechanism that allows transmission of multiple clocks, one of which is selected and regenerated at the decoder.

A multi-program transport stream is more than just a multiplex of data, audio and/or video PESs. In addition to the compressed audio, video and data, a transport stream may include metadata describing the bit stream. This includes the program association table (PAT) that lists every program in the multi-program transport stream. Each entry in the PAT points to a program map table (PMT) that lists the elementary streams making up each program. Some programs will be unencrypted, but some programs may be subject to conditional access (encryption) and this information is also carried in the metadata. The transport stream can be comprised of fixed-size data packets, for example, each containing 188 bytes. Each packet can carry a program identifier code (PID). Packets in the same elementary stream can all have the same PID, so that the decoder (or a demultiplexer) can select the elementary stream(s) it wants and reject the remainder. Packet continuity counts ensure that every packet that is needed to decode a stream is received. A synchronization system can be used so that decoders can correctly identify the beginning of each packet and deserialize the bit stream into words.

A content item, such as a program, can be a group of one or more PIDs that are related to each other. For instance, a multi-program transport stream used in digital television might contain three programs, to represent three television channels. Suppose each channel consists of one video stream, one or two audio streams, and any necessary metadata. A receiver wishing to tune to a particular “channel” merely has to decode the payload of the PIDs associated with its program. It can discard the contents of all other PIDs.

The multi-program transport stream carries many different programs, and each may use a different compression factor and a bit rate that can change dynamically even though the overall bit rate stays constant. This behavior is called statistical multiplexing and it allows a program that is handling difficult material to borrow bandwidth from a program handling easy material. Each video PES can have a different number of audio and data PESs associated with it. Despite this flexibility, a decoder must be able to change from one program to the next and correctly select the appropriate audio and data channels. Some of the programs can be protected so that they can only be viewed by those who have paid a subscription or fee. The transport stream can comprise Conditional Access (CA) information to administer this protection. The transport stream can comprise Program Specific Information (PSI) to handle these tasks. In an aspect, the transport stream or other data stream can comprise event notifiers, tags, flags, or signals. As an example, the event notifier can represent a time slot for an advertisement or an alternate content. As a further example, the event notifier can represent a blackout of content. In an aspect, the event notifiers can be dependent upon the user location receiving the stream. As an example, a national advertisement can be replaced by a local advertisement in response to an event notifier. As a further example, a local programming can be subject to blackout, while other locales have permission to present the programming.

As described in greater detail below, provided are methods and systems for controlling content in response to processing repeatedly embedded signals. In an aspect, a placement signal can be repeatedly embedded in a fragmented data stream that is transmitted to a user device. Accordingly, as the user device processes the data stream, the user device can process the repeatedly embedded signal in order to control a content. As an example, the placement signal can be embedded based upon a particular event, such as an advertisement spot, alternative content, and/or programming blackout.

FIG. 2 is a block diagram of an exemplary content control system 200. The system 200 can comprise one or more data sources 202 for accessing and/or transmitting data, such as a data stream, an encoder 204 in signal communication with the data source 202, and a fragmentor 206 in signal communication with the encoder 204. As an example, the encoder 204 and the fragmentor 206 are integrated as part of a unitary device. However, the encoder 204 and the fragmentor 206 can be separate and distinct components.

In an aspect, the data sources 202 can comprise a content provider (e.g. audio content, video content, data, news feed, sports programming, advertisements, etc.) configured to transmit the data (e.g., as a stream, fragments, files, etc.) to various end-users. In an aspect, one or more data source 202 can comprise an advertisement database having a plurality of advertisements stored therein or capable of accessing advertisement stored elsewhere. As an example, the advertisement database can comprise a plurality of video advertisements. As a further example, the plurality of advertisements can each have a particular time duration associated therewith. In an aspect, the time duration associated with the advertisements or alternate content can be varied in duration for application in various time dependent circumstances. As an example, a particular advertisement can have multiple versions, wherein each version of the same advertisement can have a different time duration. Accordingly, an advertisement having a particular time duration can be retrieved to fill a time slot having a substantially equal time duration. However, any advertisement or advertisements can be retrieved or transmitted to the end user.

As an example, one or more of the data sources 202 can comprise a network data feed transmitting the data stream to users such as subscribers or clients. As a further example, the one or more data source 202 can be configured to transmit the data stream in a standard video format, such as, but not limited to, any of the Moving Picture Experts Group standards (e.g., MPEG-2, MPEG-4, a single MPEG-4 video encapsulated in an MPEG-2 transport stream over UDP MCAST, etc.), or any of the standards for audio and/or video, such as MP3, Quicktime, and Audio Video Interleave (avi). However, the encoder 204 can be configured to receive the data stream from any source having any format that can be encoded (or transcoded) into a format that is appropriate for streaming or otherwise transmitting.

The encoder 204 can be any device, system, apparatus, or the like to encode and/or transcode the data stream. In an aspect, the encoder 204 converts a single (high) bit rate to an output of multiple (lower) bitrates. As an example, the encoder 204 can convert the data stream from the input format received from the data source (such as MPEG-2) to a transport format for distribution to consumers (such as MPEG-4). In an aspect, the encoder 204 can be a device such as a transcoder that conditions streaming data and/or changes it from one format to another. The encoder 204 can be configured to receive the data stream, or other type of signal, from one or more of the data source 202 and encode/transcode information onto the data stream. In an exemplary embodiment, the encoder 204 adds information to the signal relating to content fragments 208.

In an aspect, the fragmentor 206 can be in signal communication with the encoder 204 to receive the data stream therefrom. As an example, the fragmentor 206 and the encoder 204 are configured as a unitary device. However, the fragmentor 206 and the encoder 204 can be integrated or separate. In an aspect, fragmentor 206 conditions the data stream (or other data signal) for downstream distribution by a server 210 through a content distribution network 212 to user devices 214 (e.g. the decoder 120) of the content. In an aspect, the server 210 can be an origin Hypertext Transfer Protocol (HTTP) server. However, other servers an be used. As an example, the fragmentor 206 can communicate with the server 210 using the POST method of the HTTP. However, other protocols and communication methods can be used.

In an exemplary embodiment, the fragmentor 206 separates or fragments the data stream into each of the content fragments 208 represented by the data stream based upon an information encoded onto the data stream by the encoder 204. In an additional exemplary embodiment, the fragmentor 206 accesses the information encoded/inserted in the data stream by the encoder 204 to define the content fragments 208 based on, among other things, boundaries, grouping, timing, and duration from the encoded data stream. Once the content fragments 208 are generated, the content fragments 208 can be transmitted to the content distribution network (CDN) 212 for delivery to the user devices 214 for consumption (e.g., playback). As an example, the server 210, CDN 212, and the user devices 214 can intercommunicate using the GET method of HTTP. However, other protocols and communication methods can be used.

In an aspect, one or more of the user devices 214 can comprise a buffer 216. As an example, the buffer 216 can comprise a memory or a storage device. As a further example, a number of the content fragments 208 can be loaded into the buffer 216 and stored for playback by the associated user device 214. However, other data, content, and/or information can be stored in the buffer 216 such as advertisements and alternative content, for example. In an aspect, the buffer 216 can be separate from the user device 214. For example, the buffer 216 can be located upstream of the user device 214 and downstream of the CDN 212. As a further example, the buffer 216 can store information to be transmitted to any number of user devices 214 or other recipient devices. Accordingly, the user device 214 can retrieve the content fragments 208 from the buffer 216 for playback without having to communicate with the CDN 212, thereby reducing latency in playback. In an aspect, the user device 214 can process a continuous streaming track, which can comprise audio, video, or other data from the server 210 with a regular cadence (e.g., every two seconds, four seconds, ten seconds). As an example, a sparse data track can be transmitted to the user device 214 based upon irregular requests, and can comprise sporadic data, such as closed captions, commentary, advertisements, or information relating to the insertion of content such as advertisement, blackouts, and/or alternative content. Other data and tracks can be received and processed by the user devices.

In an aspect, a placement opportunity server 218 (e.g., Placement Opportunity Information Service (POIS)) can be in communication with one or more of the encoder 204 and the fragmentor 206. As an example, when the fragmentor 206 receives a data stream comprising an event identifier (e.g., advertisements identifier, content identifier, blackout identifier, flags, and/or markers) the fragmentor 206 can communicate a message comprising control information 300 to the placement opportunity server 218, as shown in FIG. 3.

In an aspect, the control information 300 can indicate that an event, such as a placement opportunity, is represented in the data stream or signal. Accordingly, the placement opportunity server 218 can process the control information 300 and can transmit a placement signal 302 to the fragmentor 206 for insertion into the data stream. In an aspect, the placement signal 302 can comprise a time duration of an available time slot (e.g. advertisement time slot) based upon the control information 300 and/or associated with the event. As an example, the placement opportunity server 218 can control a frequency by which the fragmentor 206 inserts/embeds the placement signal 302 into the data stream. As a further example, the fragmentor 206 can insert the placement signal 302 into the data stream during at least the duration of the available time slot. In an aspect, the placement signal 302 can be transmitted to the user device 214 without being inserted into the data stream, such as an independent transmission or insertion into another signal.

In an aspect, the placement signal 302 can comprise a sparse data track. As an example, the placement signal 302 can comprise data relating to a particular event represented in the data stream. As a further example, the placement signal 302 can comprise a message, such as an XML message, json, or binary encoded message, that can be embedded into a data stream. As an example, the placement signal 302 can comprise a message format as shown below:

EmbeddedSiqnal.xsd <?xml version=“1.0” encoding=“UTF-8” standalone=“yes”?> <schema version=“1.0” xmlns=“  elementFormDefault=“qualified”  targetNamespace=“  xmlns:tns=“> <element name=“altContent” type=“tns:altContent”/> <complexType name=“altContent”>  <sequence> <element name=“uid” type=“string” minOccurs=“1” /> <element name=“action” type=“tns:action” minOccurs=“1”/> <element name=“locations” type=“string” minOccurs=“1” maxOccurs=“unbounded”/> <element name=“uri” type=“string” minOccurs=“1”/>  </sequence>  </complexType>  <simpleType name=“action”>  <restriction base=“string”> <enumeration value=“START”/> <enumeration value=“STOP”/>  </restriction>  </simpleType> </schema>

However, the placement signal 302 can have any format and can be transmitted independently. In an aspect, the placement signal 302 can be inserted in a header, metadata, digest, and/or manifest, for transmission to a recipient device.

In an aspect, the placement opportunity sever 218 and/or the fragmentor 206 can control a frequency by which the placement signal 302 can be embedded/inserted/modified in the data stream based upon the time duration of the associated available time slot. As an example, a content provider can embed the placement signal 302 in a source data stream or signal. However, the frequency of these embedded placement signals 302 can be modified by a downstream device (e.g., content provider embeds placement signal 302 every 30 seconds, and the placement opportunity sever 218 and/or the fragmentor 206 add placement signals 302 such that the placement signal 302 are repeated every 10 seconds). Any frequency and distribution can be used.

In an aspect, the time duration of an available time slot can be 40 seconds and can comprise ‘n’ number of content fragments 208, as illustrated in FIG. 4, wherein each content fragment 208 can comprise a plurality of group-of-picture frames (e.g. I-, P-, and B-frames) for representing underlying content. However, other formats, content, and data can be represented by the content fragments 208. As a further example, the frequency of insertion of the placement signal 302 can be set to 2 seconds, thereby inserting the placement signal into the content fragments 208 sequentially every 2 seconds. However, any frequency can be used.

Returning to FIG. 2, a decision server 220 can be in communication with one or more of the user devices 214. In an aspect, the decision server 220 can be in communication with one or more data sources 202 and/or an origin server (e.g. server 210). As an example, the decision server 220 can be an advertisement decision server for selecting and/or transmitting advertisements to the user device 214. In an aspect, the user device 214 can be configured to query the decision server 220 in response to receiving and/or processing one of the placement signals 302. As an example, each of the placement signals 302 can comprise instructions to cause the user device 214 to request particular content to be delivered to the user device 214 in response to the placement signals 302. As a further example, the user device 214 transmits a query or request to the decisions server 220 in response to processing one of the placement signals 302. In an aspect, the user device 214 can be configured to ignore repeated ones of the placement signals 302 so that a query is not initiated for each and every processed placement signal 302. Accordingly, the decision server 220 can receive the query or request and can control the content being transmitted to the user device 214.

In an aspect, the decision server 220 can determine whether particular content data (e.g., advertisement, blackout screen, alternative programming content, etc.) should be transmitted to the user device 214. As an example, the content data can be transmitted directly to the user device 214 from source 202. However, the content data can be routed through the CDN 212 or other network. As a further example, the content data can be retrieved directly from one or more of the data sources 202 or from an origin server such as the server 210. In an aspect, content data can be spliced into the content fragments 208 received at the user device 214 based upon an instruction from the decision server 220.

As described in greater detail below, provided are methods for embedding a signal for use in controlling content transmitted to a user device. In an aspect, a placement signal can be repeatedly embedded in a data stream to ensure that a recipient device will process the placement signal in an efficient and timely manner.

FIG. 5 illustrates an exemplary method for controlling content placement. The method illustrated in FIG. 5 will be discussed in reference to FIGS. 1-4, for example only. In step 502, data can be received by a data packaging device (e.g., the fragmentor 206). In step 504, when the data comprises an event signal, marker, or the like, the data packaging device transmits a message to the placement opportunity server 218 to inform the placement opportunity server 218 of the event signal.

In step 506, the placement opportunity server 218 processes the message and returns the placement signal 302 to the fragmentor 206, wherein the placement signal 302 comprises information relating to the time duration of the event associated with the event signal. In an aspect, the time duration of the event can be used to determine a frequency by which the placement signal 302 can be transmitted and/or inserted into a data stream that can be transmitted to one or more of the user device 214, as shown in step 508.

As described in greater detail below, provided are methods for controlling content presented to a user device in response to processing an embedded signal. As an example, a placement signal can be embedded in a data stream based upon a particular event such as an advertisement spot, alternative content, and/or programming blackout. Accordingly, when a recipient device processes the placement signal, a content associated with the particular event can be presented via the recipient device.

FIG. 6 illustrates an exemplary method for controlling content placement. The method illustrated in FIG. 6 will be discussed in reference to FIGS. 1-4. In step 602, a data can be received by one or more of the user devices 214. In an aspect, the data received by the user devices 214 can comprise content fragments 208. As an example, the data received by the user devices 214 can comprise the repeatedly embedded placement signals 302. As a further example, the data received by the user devices 214 can comprise a plurality of the placement signals 302 transmitted to the user devices 214 based upon a pre-determined frequency.

In step 604, the user device(s) 214 receiving the placement signal(s) 302 can process the signal. In an aspect, the placement signal(s) can comprise information relating to a particular content and/or a time duration associated with a particular event.

In 606, the user device(s) 214 processing the placement signal(s) 302 can transmit a message, query, request, or the like to the decision server 220 in order to determine content to be presented on the user device.

In an aspect, the decision server 220 can determine whether particular content data (e.g., advertisement, blackout screen, alternative programming content, etc.) should be transmitted to the user device 214. As an example, the content data can be transmitted directly to the user device 214. However, the content data can be routed through the CDN 212 or other network. As a further example, the content data can be retrieved directly from one or more of the data sources 202 or from an origin server, such as the server 210. In an aspect, content data can be spliced into and/or between the content fragments 208 received at the user device 214 based upon an instruction from the decision server 220.

In an aspect, the user device 214 can receive content from a first channel of the data stream. As an example, the user device 214 can receive a command to change to a second channel or portion of the data stream, generate a mosaic of multiple videos, and/or generate a picture-in-picture. As a further example, the command to change can be transmitted from any control device, such as a remote control device or software. In an aspect, the change to the second channel occurs during a time duration of a particular event. Since the placement signal 302 has been repeatedly embedded in the data stream, the at least one of the embedded placement signals 302 can be processed by the user device 214 during the time duration of the event. Accordingly, the user device 214 can be configured to receive content from the second channel, wherein the content provided from the second channel can be determined based on the embedded placement signal 302.

As described in greater detail below, provided are systems for controlling content transmitted to a user device in response to processing an embedded signal. In an aspect, the methods and systems disclosed can utilize one or more computers to perform one or more functions in one or more locations.
